c = 10t (first answer choice)
Explanation:
Let's say we had 1 table. This would mean we have 10 chairs.
Now let's say we had 2 tables. So we now have 2*10 = 20 chairs.
If we had 3 tables, then we have 3*10 = 30 chairs. And so on.
The rule is:
number of chairs = 10*(number of tables)
We can shorten that down to
c = 10*t
c is the number of chairs and t is the number of tables. The letters are placeholders for positive whole numbers. You can think of them as boxes where a number will go inside.
